Shimadzu TOC-V CPH Total Organic Carbon Analyzer (Refurbished)

Overview

The Shimadzu TOC-V CPH is a high-performance, thermocatalytic total organic carbon analyzer engineered for precise, trace-level quantification of organic carbon in aqueous matrices. It operates on the principle of high-temperature catalytic combustion (680 °C) followed by non-dispersive infrared (NDIR) detection of evolved CO₂ — a method validated and standardized under JIS K 0102, ISO 8245, and ASTM D7573. This architecture ensures robust oxidation of refractory organics—including humic substances, surfactants, and low-molecular-weight acids—without requiring UV/persulfate pretreatment. The TOC-V CPH integrates seamlessly with the TNM-1 total nitrogen module, enabling concurrent TOC and TN analysis for comprehensive water quality assessment in compliance with regulatory frameworks governing pharmaceutical water systems (USP , EP 2.2.44), environmental monitoring (EPA Method 415.3), and semiconductor process water specifications.

Key Features

• High-temperature catalytic oxidation furnace (680 °C) with Pt-coated ceramic catalyst for complete, reproducible carbon conversion across diverse sample types
• Dual-detector NDIR system with automatic baseline correction and zero-point stabilization for enhanced signal stability and long-term drift control
• Integrated acidification/sparging unit for selective inorganic carbon (IC) removal prior to TOC measurement, minimizing interferences from carbonate/bicarbonate species
• Modular expandability: Fully compatible with Shimadzu TNM-1 total nitrogen module for simultaneous TOC/TN determination and calculation of TOC/TN ratios
• Robust hardware architecture designed for unattended operation in regulated environments — includes internal pressure monitoring, gas flow validation, and real-time diagnostic logging
• Pre-configured calibration protocols supporting multi-point linear and quadratic regression per USP/EP requirements

Sample Compatibility & Compliance

The TOC-V CPH accepts liquid samples ranging from ultrapure water (UPW) to wastewater, saline solutions, and mildly acidic/basic matrices (pH 2–12). Its sample introduction system accommodates direct injection (via syringe or loop) or automated analysis using the ASI-V autosampler (60-position vial capacity). All operational parameters — including combustion temperature, sparge time, acid dosage, and integration window — are programmable and stored with full version-controlled method files. The instrument meets GLP/GMP data integrity requirements: software enforces user authentication, electronic signatures, and immutable audit trails per FDA 21 CFR Part 11. Certificate of Conformance and factory calibration records are provided with each refurbished unit.

Software & Data Management

Control and data acquisition are managed via Shimadzu’s TOC-L Series software (v3.x), a Windows-based platform supporting method development, sequence scheduling, real-time chromatogram visualization, and automated report generation. Raw detector signals, calibration curves, QC check results, and system suitability test logs are stored in encrypted, timestamped binary files with SHA-256 hash verification. Export formats include CSV, PDF, and XML for LIMS integration. Audit trail functionality logs all user actions — method edits, result overrides, calibration events — with operator ID, timestamp, and pre-/post-change values. Software validation documentation (IQ/OQ templates) is available upon request.

Applications

• Pharmaceutical water systems: Purified Water (PW), Water for Injection (WFI), and Clean Steam condensate testing per USP and EU Annex 1
• Environmental laboratories: Surface water, groundwater, and wastewater effluent monitoring under EPA, ISO, and national regulatory mandates
• Power generation: Boiler feedwater and condensate purity assurance in thermal and nuclear facilities
• Electronics manufacturing: UPW qualification for wafer cleaning processes (SEMI F63)
• Academic and contract research: Method development for emerging contaminants, biodegradation studies, and carbon mass balance modeling

FAQ

Is this unit fully refurbished and performance-verified?
Yes. Each TOC-V CPH undergoes full functional recalibration, catalyst replacement, NDIR cell cleaning, gas line leak testing, and multi-level system suitability verification against certified TOC standards (e.g., potassium hydrogen phthalate, sucrose) prior to shipment.
What documentation accompanies the instrument?
You receive a Certificate of Refurbishment, calibration report (traceable to NIST SRMs), JIS/ISO compliance summary, software license transfer confirmation, and complete set of operational manuals in English.
Can the system be configured for TOC-only or TOC/TN operation?
The base configuration includes TOC-V CPH and ASI-V. The TNM-1 module is optional but fully interoperable; both configurations support independent or synchronized acquisition modes.
Is remote support and application assistance available post-purchase?
Yes. Technical support includes installation guidance, method optimization consulting, and troubleshooting via secure remote desktop — included for the duration of the 6-month warranty period.
Are spare parts and consumables readily available?
All critical consumables — catalyst tubes, NDIR cells, acid reagents, and ASI-V vials — are stocked and shipped globally within 3 business days. Shimadzu OEM part numbers are provided with each quotation.
